A companion series of movable rails or bars Each pressure and suction head 13 is slid- 65 5 are arranged intermediate of the fixed rails ingly mounted on one or more guide rods 15 fixedly secured,.in transverse spaced relation sure and suction means whereby an effective 5 depending from longitudinal rails 16 of the overhead frame 14 aforesaid, said rails being in turn slidingly mounted on transverse end rails 17 of the frame 14. 1

The vertical yielding movement of each head 13 is effected on the rods 15 against the tendency ofsprings 18, preferably encircling said rods, to maintain the head 13' in its down position and at rest upon a stop collar on the lower end .of eachrod 15. The longitudinal yielding movement of each head 13 is attained by a sliding movement upon the longitudinal rails 16, aforesaid, against the ten- .dency ofsprings 18 bearing against opposite sides of said head with a tendency to return and yieldingly maintain the head in a normal position midway of said springs.

. Inthe construction shown, adjustable stop colla-rs 20 on the longitudinal rails 16, provide adjustable abutments for the adjacent ends of a pair of springs19, and afford means for regulating thetension of the same.

With a view to a vertical adjustment of the pressure of suctionheads 13 with relation to the fixed and movable rails 3 and aforesaid, tocompensate for varieties of the quantity or nature of the stock undergoing treatment, the overhead frame 14 is carried by vertical -corner posts 21 adapted for manual turning movement andprovided with screw threaded upper ends having engagement in correspondinglyformed sockets on the frame 14, as shown.

The pressure and suction heads 13 of the present construction are of an open bottom conical form, the closed apex of each of which is slidingly mounted on its guide rod 15, as-

above described. I11 the preferred construction shown, an auxiliary cone shaped head 13 of a smaller size than the main head 13, is fixed inside the he'adfl3, with the bottom margin ofv the head 13 a short distance above that ofthe head 13, as shown.

The stock to be washed, either textile fabupon the receiving ends of the longitudinal fixed and movable rails 3 and 5. With the mechanism in operation, the movable rails 5 act to gradually move the stock along the tank 1 and beneath the pressure and, suction heads 13 and in the gradual passage of the" stockvbeneath said heads, the same is repeatedly pressed up against, the open bottom of theheads 13, causing the airconfined. in said heads to impart a downward movement of the washing fluid through said stock as: the same is moved upward by the movable rails With a succeeding downward movement of the stock an upward movement of the washingfluid throughthe same is effected by j i the suction produced in the heads 13, by such downward movement of the stock.

The o'perationof the apparatus is as fol- Repeated actions of said heads as above set forth, in the passage of the stock from one end to the other of the machine is adapted to attain a very effective washing of the stock, as the same reaches the upwardly inclined portions 3 and 5 of the fixed and movable rails 3 and 5, to be delivered automatically and gradually to press rolls 2 for a final expression of the washing fluid from the stock.
